Look at the shape. Bird's nests are usually in the shape of a marigold. High-quality marigolds have a more natural shape, with thick and dense filaments, large and thick marigolds and are not irregular. If the shape of the bird's nest is neat and beautiful, it is likely to be artificially pasted.

Look at the thickness. Bird's nests in their natural state are very thin and will be unevenly thinned with uneven cracks. Artificially pasted bird's nests tend to be thick and have no cracks, and the whole shape is smoother. In Indonesia processors will use tapioca flour to process fake bird's nests. Bird's nests made in this way are thick and neatly shaped, presenting an unnatural state.

Look at the bird's nest lines. As the bird's nest is formed in a natural state, the bird's nest lines are staggered, not neat, and present a filamentous structure, which is now the main criterion for distinguishing between real and fake bird's nests. Artificially processed bird's nests are arranged in a fine and neat manner, and consist of a flake-like structure, which is a difficult point in the production of fake bird's nests, and a breakthrough in distinguishing between real and fake bird's nests.
